In this way, the motor can control the rotation of the first air guiding air door, and through the connecting rod linkage mechanism, the second air guiding air door can rotate synchronously in the housing to jointly achieve multiple working states. However, over time and with an increasing number of uses, due to the influence of mechanical wear, the synchronization performance between the two air doors may gradually weaken. Considering the problems of reduced synchronization, stability, and durability that may be caused by the connecting rod hinge structure, a new air door adjustment structure is proposed.

[0033] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0034] As Figures 1 to 7 shown, an integrated air damper adjustment structure includes: an air outlet housing 1 and an air guiding assembly 2.

[0035] The structure of the air outlet housing 1 is provided with an air inlet port 10 and an air outlet port 11. The inner part of the air outlet port 11 is divided into two independent air outlet channels, namely the first air outlet channel 100 and the second air outlet channel 101. Both of these channels are in communication with the air inlet port 10, allowing air to flow in and out smoothly. In this embodiment, the core component of the structure is a wind guiding assembly 2, which is composed of a first wind guiding damper 20 and a second wind guiding damper 21. These two dampers are attached to the air outlet housing 1 and installed by means of rotational connection, and are exactly located in the connection area between the air inlet port 10 and the air outlet port 11. In order to achieve dynamic control of the dampers, a spline shaft 102 is provided at the end of the air outlet housing 1. This spline shaft 102 can be connected to an external driving device (such as a motor, etc.) to achieve power transmission. Among them, a driving gear 103 is installed on the spline shaft 102, and one end of the first wind guiding damper 20 extends to the outside of the housing and is configured with a first driven gear 200. Similarly, the corresponding end of the second wind guiding damper 21 also extends out and is installed with a second driven gear 201. These two driven gears are both engaged with the driving gear 103. By operating the external driving member to drive the spline shaft 102 and the driving gear 103 to rotate, the first wind guiding damper 20 and the second wind guiding damper 21 can be synchronously driven to enter the first position, the second position, the third position and the fourth position on the air outlet housing 1 in sequence, so as to achieve precise switching of the damper positions.

[0036] Specifically, when the damper is in the first position, the first air outlet channel 100 is opened, while the second air outlet channel 101 is closed; in the second position, both the first air outlet channel 100 and the second air outlet channel 101 are open; when it comes to the third position, the first air outlet channel 100 is closed and the second air outlet channel 101 is opened; finally, in the fourth position, both the first air outlet channel 100 and the second air outlet channel 101 are closed.

[0037] Specifically, as Figure 1 and Figure 2 shown, a flow splitting frame 104 is provided in the air outlet housing 1. The flow splitting frame 104 divides the air outlet port 11 to form the first air outlet channel 100 and the second air outlet channel 101.

[0038] A flow splitting frame 104 is formed in the air outlet housing 1. This frame accurately divides the air outlet port 11 into the first air outlet channel 100 and the second air outlet channel 101, ensuring the directional flow of air in their respective channels.

[0039] Furthermore, as Figure 2 and Figure 5As shown in the figure, a first wind blocking portion 105 is provided on the air outlet housing 1, and the first wind blocking portion 105 is located between the air inlet port 10 and the first air outlet passage 100; when the first air guiding damper 20 and the second air guiding damper 21 are in the third position, one side of the first air guiding damper 20 abuts against the shunt frame 104, and the other side of the first air guiding damper 20 abuts against the first wind blocking portion 105.

[0040] To ensure the sealing and guiding of the damper at different positions, a first wind blocking portion 105 and a second wind blocking portion 106 are respectively provided on the air outlet housing 1. The first wind blocking portion 105 is located between the air inlet port 10 and the first air outlet passage 100. When the first air guiding damper 20 and the second air guiding damper 21 move to the third position, one side of the first air guiding damper 20 will closely adhere to the shunt frame 104, and the other side will be in close contact with the first wind blocking portion 105 to achieve a closed effect.

[0041] Furthermore, as Figure 2 and Figure 3 shown in the figure, a second wind blocking portion 106 is provided on the air outlet housing 1, and the second wind blocking portion 106 is located between the air inlet port 10 and the second air outlet passage 101; when the first air guiding damper 20 and the second air guiding damper 21 are in the first position, one side of the first air guiding damper 20 abuts against the shunt frame 104, and the other side of the first air guiding damper 20 abuts against the second wind blocking portion 106.

[0042] The second wind blocking portion 106 is located between the air inlet port 10 and the second air outlet passage 101. When the damper is in the first position, one side of the first air guiding damper 20 still contacts the shunt frame 104, and the other side abuts against the second wind blocking portion 106, ensuring the precise control of the wind direction and the effective distribution of the air flow under specific conditions.

[0043] Furthermore, as Figure 3 and Figure 6 shown in the figure, a first limiting portion 107 and a second limiting portion 108 are provided on the air outlet housing 1. The first limiting portion 107 is located on the side of the first wind blocking portion 105 close to the first air outlet passage 100, and the second limiting portion 108 is located on the side of the second wind blocking portion 106 close to the second air outlet passage 101. A track groove 109 is formed between the second wind blocking portion 106 and the second limiting portion 108; when the first air guiding damper 20 and the second air guiding damper 21 are in the fourth position, one side of the first air guiding damper 20 and one side of the second air guiding damper 21 abut against each other, the other side of the first air guiding damper 20 abuts against the first limiting portion 107, and the other side of the second air guiding damper 21 abuts against the second limiting portion 108 along the track groove 109.

[0044] In the design of the air outlet housing 1, a first limiting portion 107 and a second limiting portion 108 are specifically provided, and these two limiting portions have precise positioning functions. Among them, the first limiting portion 107 is located on the side of the first wind shielding portion 105 adjacent to the first air outlet passage 100, while the second limiting portion 108 is located on the side of the second wind shielding portion 106 close to the second air outlet passage 101. It is worth mentioning that a track groove 109 is formed between the second wind shielding portion 106 and the second limiting portion 108, and this track groove 109 plays a guiding and limiting role during the movement of the air damper.

[0045] When the first air guiding damper 20 and the second air guiding damper 21 rotate from the first position to the fourth position, one side of the two dampers fits together to achieve a fully closed state. At this time, the non-fitting side of the first air guiding damper 20 will be in close contact with the first limiting portion 107, and the first limiting portion 107 is relied on to determine the limit position of the damper; while the non-fitting side of the second air guiding damper 21 slides along the pre-designed track groove 109 until it contacts the second limiting portion 108, so as to ensure that the damper always maintains the correct movement track and in-place accuracy during the entire closing process.

[0046] Specifically, as Figure 1 shown, an external spline portion 110 is formed on the end of the spline shaft 102 far from the driving gear 103, and the external spline portion 110 can be connected to a driving member provided externally.

[0047] In the design of the spline shaft 102, the end far from the driving gear 103 is set as the external spline portion 110, and this external spline portion 110 has the function of being connected to an external driving device. By driving the spline shaft 102 to rotate through an external driving member, the operation of the entire air damper adjustment structure is driven.

[0048] Specifically, as Figure 1 、 Figure 2 and Figure 7 shown, a flow dividing plate 111 is provided on the air outlet housing 1. The flow dividing plate 111 is located at the middle position of the air outlet housing 1. The flow dividing plate 111 symmetrically divides the space of the air outlet housing 1 into two independent air outlet subsystems. Each air outlet subsystem includes an air outlet port 11, a first air outlet passage 100, a second air outlet passage 101, a first air guiding damper 20, and a second air guiding damper 21. One ends of the first air guiding dampers 20 and the second air guiding dampers 21 in the two air outlet subsystems close to the flow dividing plate 111 are rotatably connected to the flow dividing plate 111, and the other ends of the first air guiding dampers 20 and the other ends of a pair of second air guiding dampers 21 in the two air outlet subsystems all extend to the outside of the air outlet housing 1 to ensure that the first driven gear 200 and the second driven gear 201 are engaged with the driving gears 103 at the corresponding ends.

[0049] The flow dividing plate 111 symmetrically divides the internal space of the air outlet housing 1 into two independent air outlet subsystems. Each subsystem includes a complete air outlet structure: an air outlet port 11, a first air outlet channel 100, a second air outlet channel 101, a first air guiding damper 20, and a second air guiding damper 21. In the two subsystems, one ends of the first air guiding damper 20 and the second air guiding damper 21 close to the flow dividing plate 111 are connected to the flow dividing plate 111 in a rotational manner, so as to realize flexible rotational control of the dampers. At the same time, the other ends of the first air guiding damper 20 and the second air guiding damper 21 in the two subsystems will extend out of the air outlet housing 1, and ensure precise meshing with a first driven gear 200 and a second driven gear 201 on the driving gear 103 outside the air outlet housing 1, so that the dampers can quickly and accurately respond after receiving a driving signal and perform the tasks of adjusting the wind direction and air volume.

[0050] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, the directional indication will also change accordingly.
